Rhode Island State Police, Pembroke Police, Bridgewater State College Police and officers from almost every local police department turned out Friday to help with the search for the second Boston Marathon bomber.

The search locally was centered on the campus of the University of Massachusetts Dartmouth, where the suspect, 19-year-old Dzhokhar Tsarnaev, was a student.

Throughout the day Friday, convoys of police cruisers and unmarked undercover cars moved in and out of the campus, often with lights flashing and sirens on.

At least one local officer has been part of the investigation since its start.

A 10-year Fall River Police Department detective, assigned to the federal Bureau of Alcohol, Tobacco and Firearms, has been working with Boston police since Monday’s Boston Marathon, according to Deputy Police Chief Al Dupere.

“He’s been engaged in the investigation and search for suspect Number 2,” said Dupere of his officer searching for Tsarnaev, identified as the suspect at-large.

The officer — whom the chief did not identify because of his work with the ATF on Greater Fall River investigations — provided his city department with updates, Dupere reported.

The Bristol County Sheriff’s Office was ready to respond but was not called for personnel or the department’s mobile command center, according to the office of Sheriff Thomas Hodgson.
